Computer help forum: Computer not booting up

I have a Dell xps l702x laptop running windows 7 home.It has run fine until yesterday. Tried to boot it up and the dvd made noise and then the cpu fan came on and then nothing else. None of the normal lights came on and nothing on the monitor nor did it try to post. In trying to shut it down I held the power button for a while but it would not turn back off. I had to unplug the power supply and take out the battery. Thanks for anyones help.

Try to drain the residual power from the laptop:-Disconnect any external peripherals (flash drives, printers, external hard drives) from the computer-Then remove the adapter and the battery-Press and hold the power button for 10 seconds-Reconnect the battery and the adapter-Try to restart the computer and check

If the system powers back on, then I would suggest you to run the Dell Diagnostics to check the hardware functionality. Power off the computer -> restart the computer, press 'F12' key on the Dell logo -> Select 'Diagnostics' from the boot menu.

Already drained flee power. Oddly enough before I did it the laptop wouldn't even show the adapterwas plugged in. After it started in the same manor but the power adapter light showed that the powersupply was plugged in.

It the system does not power on at all, then it might be an issue with the motherboard or the DC-in port and may require replacement. I would suggest you to try an alternate AC Adapter and check. Else, the suggested part replacement would the the DC-in port first. The issue issue persists, then the motherboard wold have to be replaced.

Here a good laptop might come back if I remove the battery and drives and maybe the WiFi card and leave it at one stick of RAM. This is the common bare minimum to see the screen light up with the boot details. It's not supposed to boot but it can let me see if the issue is the laptop or the items I removed.Bob

Did all this. Not helping. May have got a power surge that nuked the mainboard as we had lots ofstorms in the area that night. Se la vie. Going to buy another one on ebay cause I love it and alsoI need a workstation computer. Then I can do cross diagnostics to figure out this ones problem and fixit also.
